Every tuner out there would love to customize a Mercedes CLS63 for once, and this time its GAD group who have customized the Mercedes CLS 63 into a beast, all thanks to its 5.5 liter bi-turbo V8 engine.
The tuner first of all looked up under the hood, at which the 5.5 liter engine which used to pump out 557 hp and 800 Nm of torque, and then they customized the engine, adding turbochargers with GAD’s own units, a new set of cooling system, optimizing manifolds, installing a full sport exhaust system with downpipe, race catalysts and valved mufflers, and finally tweaking the software with new boost pressure and ignition timing data, they also ditched the speed limiter. All this resulted in a whopping deliverance of 803 hp and 1,150 Nm of torque, which means that the Merc can now run beyond the 300 km/h mark. This whole engine treatment would cost 25,600 Euros. And a full package would cost more than 50 grand!
Take a look at the pictures, and stay tuned for more updates on SpeedLux.
